Ephedrae Herba (Mahuang, 麻黄) four liang, Armeniacae Semen Amarum (Xingren, 杏仁) fifty seeds (soaked, skin and tips removed), Glycyrrhizae Radix et Rhizoma (Gancao, 甘草) two liang (roasted), Gypsum Fibrosum (Shigao, 石膏) eight liang (crushed, wrapped in silk gauze).
The above four ingredients, use seven sheng of water, first boil Ephedrae Herba until the volume reduces by two sheng, remove the foam on the surface [decoction method], then add the other herbs, boil to obtain two sheng of liquid, filter out the dregs [decoction method],
and take warm.
For patients with a history of wheezing (Chuanjia, 喘家) taking Guizhi Tang (Cinnamon Twig Decoction), adding Polygeli Tuber (Coupsu, 厚朴) and Armeniacae Semen Amarum is used to treat cold-type wheezing. Now, using Ephedrae Herba and Gypsum Fibrosum added with Armeniacae Semen Amarum is used to treat heat-type wheezing. Ephedrae Herba opens the pores (Maokiao, 毛窍),
Armeniacae Semen although
the treatment methods still retain the meaning of distinguishing between Ying (Nutrient) and Wei (Defensive) levels.
Ephedrae Herba two liang (nodes removed), Aconiti Lateralis Radix Praeparata (Fuzi, 附子) one piece (processed, skin removed, cut into eight slices), Glycyrrhizae Radix et Rhizoma two liang (roasted).
The above three ingredients, use seven sheng of water, first boil Ephedrae Herba for one or two boils, remove the foam on the surface [decoction method], then add the other herbs, boil to obtain three sheng of liquid, filter out the dregs [decoction method],
and take warm.
In Shaoyin disease (Shaoyin Bing, 少阴病) without interior symptoms, if sweating is desired, prepared Aconiti Lateralis Radix should be used to secure the Kidney Qi, preventing Ephedrae Herba from penetrating deeply into the Kidney meridian to rob body fluids for sweat. More ingeniously, Glycyrrhizae Radix moderates the potency of Ephedrae Herba,
Ephedrae Herba two liang (nodes removed), Asari Radix et Rhizoma (Xixin, 细辛) two liang, Aconiti Lateralis Radix Praeparata one piece (processed, skin removed, broken into eight pieces).
The above three ingredients, use one dou of water, first boil Ephedrae Herba until the volume reduces by two sheng, remove the foam on the surface [decoction method], then add the other herbs, boil to obtain three sheng of liquid, filter out the dregs [decoction method],
take one sheng warm [administration method], three times a day [administration method].
When Shaoyin disease is complicated by heat from Taiyang, Ephedrae Herba is used to induce sweating from the Taiyang exterior, while Asari Radix et Rhizoma disperses the floating heat of Shaoyin; they act synergistically. It is intended to guide
Ephedrae Herba
Kidney root
Ephedrae Herba two liang and half (nodes removed), Cimicifugae Rhizoma (Shengma, 升麻) one liang and one fen, Angelicae Sinensis Radix (Danggui, 当归) one liang and one fen, Anemarrhenae Rhizoma (Zhimu, 知母) eighteen zhu, Scutellariae Radix (Huangqin, 黄芩) eighteen zhu, Polygonati Odorati Rhizoma (Weirui, 葳蕤)

The above fourteen ingredients, use one dou of water, first boil Ephedrae Herba for one or two boils, remove the foam on the surface [decoction method], then add the other herbs, boil to obtain three sheng of liquid, filter out the dregs [decoction method],
divide into three warm doses [administration method]. The interval between doses should be approximately the time it takes to cook three dou of rice, consume all the medicine [administration method], recovery occurs with sweating.
Mahuang Shengma Tang (Ephedra and Cimicifuga Decoction) contains various methods including ascending and dispersing, cooling and moistening, astringing and moderating, and draining and purging. Analyzing its emphasis, it focuses on raising Yang within Yin, thus using Ephedra and Cimicifuga
